Uterus

The uterus is essential for survival of the species. It is commonly afflicted with tumours.

Endometrium and its pathology is dealt with in the endometrium, endometrial hyperplasia and endometrial carcinoma articles.

Other tumours are dealt with in uterine tumours.

Operations

  • Myomectomy.
  • Subtotal hysterectomy.
    • Discouraged... as the cervix remains and can develop a cancer.
  • Total hysterectomy.
  • Radical hysterectomy - total hysterectomy + parametrial tissue.[2]
    • Indications: cervical cancers, advanced uterine cancers.
      • This is typically done by gynecologists with additional training at larger centres.
      • Usually done with a bilateral salpingo-opherectomy (both tubes and ovaries) and pelvic lymph node dissection.

Notes:

  • There are almost no quality of life differences between total & subtotal hysterectomy.[3]
  • Simple hysterectomy is removal of the uterus and cervix;[4] it can be used as a synonym for total hysterectomy.[5]

Grossing hysterectomy specimens

Hysterectomy specimens - orientation

Orientation:

  • Less peritoneum on anterior (as the urinary bladder is there).
    • Posterior peritoneal edge: pointy (upside down triangle).
      • Anterior peritoneal edge: rounded/non-pointy.
  • Tubes on anterior-lateral aspect.[6]
    • Round ligaments posterior to tubes.

Normal uterine wall

Gross

  • Firm.
  • Pear-shaped.
    • Not quite true -- it is usu. flattened at the anterior and posterior.

Negatives:

  • No nodules.
  • No trabeculations.

Microsopic

Features:

  • Smooth muscle arranged in fascicles.

IHC

  • ER +ve.
  • PR +ve.

Tumours of the corpus

The most common is leiomyoma (uterine fibroids).

Endometrium

Dealt with in endometrium, endometrial hyperplasia and endometrial carcinoma articles.

Specific conditions

Congenital absence of the uterus

General

  • Often associated with absence of the deep portion of the vagina; thus, may be congenital absence of the uterus and vagina (CAUV).
  • May go by the name Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome.[7]
  • May be seen in the context of Müllerian agenesis. (???)

Features:[7]

  • Subdivided - as etiologies differ.
  • Thought to have a genetic component - autosomal dominant with variable penetration.

Treatment:

  • Uterine transplant - attempted.[8]

Uterus didelphys

General

  • Benign - though may adversely affect fertility.[9]
  • Rare - seen in < 0.3% deliveries.[10]
  • Can be thought of as double uterus - a consequence of the Muellerian ducts not fusing.

Related conditions:

  • Arcuate uterus - fundus has a concave contour towards the uterine cavity.
  • Septate uterus.
  • Bicornuate uterus.
  • Uterus didelphys.

Microscopic

  • Non-specific - gross diagnosis.

Uterine adenomyosis

  • AKA adenomyosis of the uterus.

Dysfunctional uterine bleeding

  • Abbreviated DUB.

General

  • Clinical diagnosis based on negative pathology - specifically a negative endometrial biopsy.
